Answer:
the price of each kind of ticket is $22 and $3 respectively
Step-by-step explanation:
Let us assume the adult be x
And, the children be y
Now the equations would be
x + y = $25
x = $25 - y ............(1)
45x + 60y = $1,170
3x + 4y = $78........(ii)
Now put the x value in the equation 2
3($25 - y) + 4y = $78
$75 - 3y + 4y = $78
y = $3
x = $25 - y
= $25 - $3
= $22
hence, the price of each kind of ticket is $22 and $3 respectively
Answer:
integer and rational
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x) = 7x³ - x² - x - 5
To test if (x-1) is a factor, calculate f(x) for x=1:
f(1) = 7·1³ - 1² - x - 5 = 0
Since f(1) = 0, (x-1) is a factor.
